Olive Oil vs. Coconut Oil: Which Wins for Heart Health?

The Coconut Oil Story: Good Marketing, Weak Science

Coconut oil spent a decade being called a superfood. It showed up in wellness blogs, morning coffee routines, and nutrition advice from influencers with millions of followers. The pitch was simple: this is a healthy fat that your body handles differently, and it is good for your heart.

The science never quite backed that up.

Olive oil, on the other hand, has been studied seriously by cardiovascular researchers for more than 40 years. The evidence has gotten stronger over time, not weaker. Large clinical trials have shown meaningful reductions in heart attack and stroke rates in people who eat olive oil daily.

This article looks at both oils honestly — what they are made of, what they actually do to your cholesterol, and what the most credible health bodies in the world recommend. If you have ever wondered whether coconut oil is worth switching to, or whether the olive oil in your kitchen is already the right call, here is the clearest answer the research currently supports.

For a broader look at the long-term cardiovascular evidence on olive oil specifically: Olive Oil and Heart Health: What 40 Years of Research Has Found.

What These Oils Are Actually Made Of

The biggest difference between coconut oil and olive oil has nothing to do with taste or smoke point. It is their fat composition — and that difference has direct consequences for what happens inside your arteries.

Coconut oil is roughly 82 to 90 percent saturated fat. That is more than butter (about 63 percent) and more than lard (about 39 percent). Most people do not realize this because coconut oil has been marketed in health-food terms, but by saturated fat percentage, it is one of the highest of any common cooking fat.

The main type of saturated fat in coconut oil is called lauric acid, which makes up about half of the total fat. We will come back to lauric acid specifically because it is the heart of most arguments made in coconut oil's favor.

Extra virgin olive oil is almost the opposite. It is roughly 73 percent monounsaturated fat — a type of fat that your body handles very differently than saturated fat. The dominant fat is oleic acid, which has been studied extensively for how it affects your cholesterol levels and arteries.

Olive oil also contains about 14 percent saturated fat and 11 percent polyunsaturated fat, giving it a much more balanced profile. And beyond its fat content, it contains plant compounds called polyphenols that affect your cardiovascular health in ways that fat content alone does not explain.

Here is how the two oils compare side by side:

 

	Extra Virgin Olive Oil	Coconut Oil
Saturated fat	~14%	~82–90%
Monounsaturated fat	~73% (mainly oleic acid)	~6%
Polyunsaturated fat	~11%	~2%
Protective polyphenols	200–800+ mg/kg in quality EVOO	Essentially none
Effect on LDL	Lowers LDL cholesterol	Raises LDL cholesterol
Major heart trials	PREDIMED (7,447 participants, 5 yrs)	None at cardiovascular scale

 

Coconut oil contains essentially no polyphenols. These are the protective plant compounds in olive oil that go beyond fat type — and they are a big part of why olive oil research results look as strong as they do.

What Saturated Fat Does to Your Cholesterol

Saturated fat raises LDL cholesterol. This is one of the most consistently replicated findings in all of nutrition science. It has been demonstrated in controlled feeding studies across decades, confirmed repeatedly in randomized trials, and accepted by every major cardiovascular health organization in the world.

LDL stands for low-density lipoprotein. It is the type of cholesterol most closely linked to heart disease. When LDL levels are high, cholesterol builds up inside artery walls over time — a process that can eventually lead to a heart attack or stroke. Think of it as a slow-moving buildup that happens over years, not days.

In 2017, the American Heart Association published a major review of more than 100 randomized controlled trials on dietary fat and heart health. It covered the most detailed body of evidence on the topic that any major health body had ever assembled.

Their conclusion on coconut oil: it raised LDL cholesterol in all seven controlled trials where it was tested against unsaturated fats. You can read the full AHA advisory here.

The average LDL increase across those studies was 10.47 mg/dL — a number that most cardiologists would consider clinically meaningful. If a patient's LDL went up by that much between checkups, a doctor would want to talk about what changed.

The AHA placed coconut oil in the same category as butter and beef fat for cardiovascular risk. It did not recommend coconut oil as a heart-healthy food. That recommendation came after a thorough review of the evidence, not a casual opinion.

What the Fat in Olive Oil Does Instead

Oleic acid — the main fat in olive oil — does the opposite of what saturated fat does to your cholesterol.

When you replace saturated fat in your diet with oleic acid, LDL tends to drop. HDL — the so-called "good" cholesterol that helps clean LDL out of the bloodstream — either stays stable or rises slightly. That is the direction cardiologists want those numbers to move.

But oleic acid does something else that matters. It helps protect your cholesterol particles from getting damaged by oxygen. Damaged cholesterol — called oxidized LDL — is significantly more dangerous than regular LDL. Damaged particles are more likely to stick inside artery walls and trigger inflammation, which accelerates the buildup that leads to heart disease.

Part of olive oil's heart benefit comes from what it adds. But part comes from what it replaces. When you use olive oil instead of butter, coconut oil, or other saturated fats, you are making a shift that research consistently ties to better heart outcomes.

 

 

The Biggest Trial on Olive Oil and Heart Health

The most important clinical evidence on olive oil and the heart comes from a study called PREDIMED. It is the largest randomized controlled trial ever run specifically on diet and cardiovascular disease risk.

PREDIMED followed 7,447 people across Spain for about five years. All participants were at high risk for heart disease. They were divided into three groups: one that followed a Mediterranean diet with extra virgin olive oil, one that followed the same diet with added nuts, and one that was told to eat a low-fat diet as a control.

The olive oil group consumed about one liter of extra virgin olive oil per week — roughly four tablespoons a day.

The result: the olive oil group had a 30 percent lower risk of major cardiovascular events — heart attack, stroke, or death from heart disease — compared to the low-fat control group. The full PREDIMED results were published in the New England Journal of Medicine.

A 30 percent reduction is a large effect for a dietary change. Most drugs developed specifically for cardiovascular risk reduction aim for reductions in roughly the same range. PREDIMED achieved it through food.

No comparable trial exists for coconut oil. The coconut oil research base consists mostly of short studies measuring cholesterol numbers — not studies that tracked whether people actually had fewer heart attacks.

The "But It Raises Good Cholesterol" Argument

The most common defense of coconut oil goes like this: yes, it raises LDL, but it also raises HDL (the "good" cholesterol). So maybe the net effect on heart risk is neutral, or even positive.

This sounds reasonable but does not hold up well under the evidence.

The LDL increase from coconut oil is generally larger than the HDL increase. The ratio between LDL and HDL — which doctors use as a more reliable indicator of risk than either number alone — still moves in the wrong direction when coconut oil replaces unsaturated fat.

Harvard T.H. Chan School of Public Health reviewed the coconut oil evidence and concluded it is not a health food. The HDL bump is real but does not offset the LDL rise. Their analysis of coconut oil lays this out plainly.

There is also a broader issue with treating HDL as a direct measure of protection. Several drug trials were run specifically to raise HDL in patients — and they did not reduce heart attacks. This means HDL on its own is not as reliable a predictor as it was once thought to be. What matters is the whole picture, not a single number moving in your favor.

The Lauric Acid Argument

The most detailed argument for coconut oil centers on lauric acid — the specific type of saturated fat that makes up about half of coconut oil.

The argument is that lauric acid is processed by the body differently from other saturated fats. It behaves a bit more like a medium-chain fat metabolically, which some researchers believe means it does not raise LDL in the same harmful way as longer-chain saturated fats like the kind found in red meat.

This is not a fringe claim. Some serious researchers have raised it. But the clinical evidence does not clearly support the idea that lauric acid is harmless for your cholesterol.

The AHA reviewed the lauric acid argument in its 2017 advisory and still concluded that the LDL-raising effect was real and medically significant — whatever the underlying mechanism.

The argument for lauric acid being "different" is based on how it moves through the body at a biochemical level, not on studies showing that coconut oil users have fewer heart attacks. Those long-term outcome trials do not exist. Until they do, the honest answer is that the current evidence does not support lauric acid neutralizing the cardiovascular risk that comes with coconut oil's fat profile.

 

 

The Polyphenol Gap: Where Coconut Oil Cannot Compete

Here is where the comparison becomes the clearest.

Extra virgin olive oil contains a group of plant compounds called polyphenols. They include hydroxytyrosol, oleocanthal, and oleuropein, among others. These compounds act as antioxidants inside your body — meaning they help neutralize the kind of damage that leads to inflammation and artery disease.

They are not just a bonus. Polyphenols in olive oil help prevent LDL cholesterol from getting oxidized (damaged). They help reduce the low-level inflammation that drives heart disease over time. They are a major reason olive oil research results are as strong as they are. The oil is working through multiple pathways at once — not just its fat content.

For a plain-English guide to what polyphenols are and what they do in olive oil: What Are Polyphenols in Olive Oil and Why Do They Matter?.

The European Food Safety Authority — the EU's equivalent of the FDA for food and health claims — approved a specific health claim for olive oil polyphenols. The claim: olive oil polyphenols protect LDL cholesterol from oxidative damage. That approval is based on a review of human clinical evidence, not marketing material.

One of the most-studied polyphenols is hydroxytyrosol, which has attracted significant research attention for its antioxidant activity. For a closer look: Hydroxytyrosol: The Antioxidant Researchers Are Calling Exceptional.

Coconut oil contains essentially no polyphenols. It is a refined fat with negligible antioxidant content. So even if both oils had the same effect on cholesterol — which they do not — olive oil would still have a meaningful health advantage.

There is one catch: the polyphenol content in olive oil is not fixed. It depends entirely on how and when the oil was made. Oil that was pressed slowly, stored in clear bottles, or sitting in a warehouse for a year may have very little of these compounds left by the time it reaches you.

For a guide to what separates high-polyphenol olive oil from standard extra virgin: High-Polyphenol Olive Oil: What It Means and Why It Matters.

Damaged Cholesterol: A Risk Factor Most People Have Not Heard Of

Your standard cholesterol test measures how much LDL is in your blood. But there is a more specific version of LDL that matters even more for heart risk: oxidized LDL — LDL that has been damaged by exposure to free radicals in your bloodstream.

Damaged LDL is more likely to get stuck inside artery walls. When it does, your immune system sends cells to deal with it — and those cells become engorged with cholesterol and turn into what researchers call foam cells. Foam cells are an early building block of arterial plaques. The standard LDL test does not show you how much of your LDL is already damaged.

This is where olive oil polyphenols do something specific. Multiple clinical studies have shown that regularly consuming high-polyphenol extra virgin olive oil reduces measurable markers of oxidized LDL in the bloodstream.

Coconut oil has no polyphenol content to provide this protection. And some research suggests that high saturated fat intake may actually make LDL particles more susceptible to oxidative damage — adding a second layer of risk on top of the direct cholesterol increase.

The Cooking Stability Question

One common argument for coconut oil is that it is a safer choice for cooking because it handles heat better. The reasoning: saturated fat has fewer chemical bonds that can break down under high heat, so coconut oil should be more stable at cooking temperatures.

Refined coconut oil has a smoke point of about 400 degrees Fahrenheit. Virgin coconut oil is lower, around 350 degrees. Extra virgin olive oil falls in the 375 to 405 degree range, depending on quality — higher-polyphenol oils tend to be more stable under heat, not less.

The "olive oil cannot handle heat" claim has been tested repeatedly and does not hold up. A 2018 study in the journal Acta Scientific Nutritional Health heated multiple cooking oils at sustained temperatures and measured how much they broke down into harmful compounds. Extra virgin olive oil performed better than most other oils tested, including coconut oil. Researchers credited olive oil's polyphenols as a natural stabilizing factor.

So for home cooking — sautéing vegetables, pan-frying, roasting — olive oil is stable and appropriate. You do not need to switch to coconut oil to avoid heat damage. And whatever you cook with, the heart benefits of olive oil apply across the full range of how you use it.

What Every Major Health Body Actually Says

When you look at what established medical and nutrition organizations recommend, there is no ambiguity.

The American Heart Association does not recommend coconut oil for heart health. Its guidance is to replace saturated fats — including those in coconut oil — with unsaturated fats like those in olive oil.

The World Health Organization recommends keeping saturated fat below 10 percent of your total daily calories and replacing it with unsaturated fat where possible. See their healthy diet fact sheet.

Harvard T.H. Chan School of Public Health classifies coconut oil as something to use sparingly rather than as a daily cooking fat. It lists olive oil as a preferred fat for cardiovascular and general health.

The European Food Safety Authority approved a health claim for olive oil polyphenols linked to LDL protection, based on a formal review of human clinical evidence. See the EFSA scientific opinion. No equivalent claim has been approved for coconut oil anywhere in the world.

This is not a fringe position held by one organization. It is the consistent view across the major bodies that review nutrition and cardiovascular science. That consensus does not mean the science is fully settled on every detail — but it does mean the current evidence strongly and clearly favors olive oil.

The Verdict

On heart health, the evidence is not close.

Olive oil has decades of clinical data behind it, including the largest diet-and-heart trial ever run, which showed a 30 percent reduction in cardiovascular events. It has a fat profile that lowers LDL, polyphenols that protect your cholesterol from damage and reduce inflammation, and endorsement from every major cardiovascular health body in the world.

Coconut oil raises LDL in controlled studies, has no polyphenol content, and has no large-scale trial showing it reduces heart attacks or strokes. Its proponents make a legitimate scientific argument about lauric acid — but an argument about biochemical mechanism is not the same as clinical evidence of cardiovascular protection.

If you enjoy coconut oil for its flavor in specific dishes, using it occasionally is unlikely to cause meaningful harm. The concern is with daily use as your primary fat. On that question — choosing an everyday oil for your health — olive oil wins on every measure the research currently supports.

One More Thing: Not All Olive Oil Delivers the Same Benefit

The health research on olive oil — including PREDIMED — was done with genuine, high-polyphenol extra virgin olive oil. If the oil in your kitchen has very little polyphenol content left, you are not consuming the product that the research studied. You are getting the fat with fewer of the additional benefits.

Polyphenols start degrading the moment olives are picked. Long delays between harvest and pressing, excessive heat during extraction, exposure to light in the bottle, and extended time in transit all reduce polyphenol content significantly.

For why the time between harvest and pressing is so critical: What Happens When Olives Sit Too Long Before Pressing.

Four Hour Olive Oil is named for its production standard: olives are cold-pressed within four hours of harvest. That timeline is specifically designed to lock in polyphenol content before it degrades. The oil is bottled in dark glass and shipped directly from the producer — without going through the long intermediate storage and transport that most retail olive oil passes through.

The "extra virgin" label tells you about the oil at the time of pressing. It does not tell you about polyphenol content, and it does not tell you how much has degraded since. High-quality oil made with a short pressing timeline and proper handling is a meaningfully different product from oil that checks a regulatory box but has been sitting in the supply chain for a year.

One of the clearest signals that an oil's polyphenols are still intact is its taste. For what that taste is actually telling you: Why High-Polyphenol Olive Oil Tastes Bitter — and Why That's a Good Sign.

Frequently Asked Questions

Is coconut oil bad for your heart?

Most major cardiovascular health organizations do not classify it as heart-protective. It raises LDL cholesterol in controlled studies, and no large-scale trials show it reduces heart attacks or strokes. Using it occasionally is unlikely to cause serious harm, but it is not a protective food the way olive oil is.

Does olive oil lower cholesterol?

Yes. Regular consumption of extra virgin olive oil is consistently linked to lower LDL cholesterol. The PREDIMED trial -- the largest diet-and-heart study ever run -- found a 30 percent reduction in major cardiovascular events in people using extra virgin olive oil daily over five years.

Is coconut oil better than olive oil for cooking?

No, not on the evidence. The claim that extra virgin olive oil is too fragile to cook with is not supported by research. Studies show high-quality EVOO is stable at typical cooking temperatures and produces fewer harmful byproducts under heat than many other oils, including coconut oil. For heart health, olive oil is the better everyday choice whether you are cooking with it or using it raw.

Why did coconut oil get labeled a superfood?

The coconut oil boom was driven mainly by marketing, wellness media, and a cultural reaction against low-fat diet advice in the early 2010s. It gained momentum partly through an association with medium-chain triglycerides (MCTs), but coconut oil is not the same as pure MCT oil, and the research on MCTs cannot be applied directly to coconut oil.

What is the difference between coconut oil and MCT oil?

MCT oil is a refined product concentrated in specific medium-chain fats -- mainly caprylic and capric acid. Coconut oil contains MCTs but also large amounts of lauric acid, which behaves differently in the body. The two are not interchangeable, and studies on MCT oil cannot be used as evidence for coconut oil's heart benefits.

Which oil does the Mediterranean diet use?

Olive oil. The Mediterranean diet is built around olive oil as its primary fat. All major clinical trials on the Mediterranean diet -- including PREDIMED -- used olive oil as the main fat source. The cardiovascular benefits attributed to that diet pattern are based on olive oil, not coconut oil.

Does coconut oil raise your LDL?

Yes. The American Heart Association reviewed the evidence in 2017 and found that coconut oil raised LDL in all seven controlled trials where it was compared directly to unsaturated fats, with an average increase of about 10.47 mg/dL.

Does the type of coconut oil matter -- virgin versus refined?

For flavor, yes. Virgin coconut oil has more distinct taste compounds. For heart health, both versions have the same core issue: very high saturated fat content that raises LDL. Neither version contains meaningful polyphenols. The virgin distinction does not change the cardiovascular concern.

How much olive oil per day is good for your heart?

The PREDIMED trial used about four tablespoons (60 ml) per day. Most nutrition guidance points to one to four tablespoons as a practical daily range. Consistency matters more than hitting an exact amount -- the research supports daily use, not occasional use.

Does olive oil have more antioxidants than coconut oil?

Yes, significantly. High-quality extra virgin olive oil contains protective plant compounds called polyphenols -- including hydroxytyrosol, oleocanthal, and oleuropein -- that act as antioxidants and help prevent LDL damage. The European Food Safety Authority has approved a health claim for olive oil polyphenols based on human clinical evidence. Coconut oil contains none of these compounds, essentially.

What does the American Heart Association say about coconut oil?

In its 2017 advisory on dietary fats, the AHA did not recommend coconut oil for heart health. It found that coconut oil raised LDL in controlled trials and recommended replacing saturated fats -- including those in coconut oil -- with unsaturated fats like those found in olive oil.

Can I use both oils?

Yes. If you enjoy coconut oil for specific dishes or its flavor, occasional use is unlikely to cause meaningful harm. The issue is with daily use as your primary cooking fat. A sensible approach: use olive oil as your default for everyday cooking and dressings, and reach for coconut oil occasionally when you specifically want what it brings to a dish.
